From the given alternative words, select the word which can be formed by using the letters of the word COMMUNICATION.

Introduction / Context:
This question reverses the previous pattern and asks which word can be formed using the letters of COMMUNICATION. Here only one of the given options is possible to construct from the base word, while the others require letters that are missing or require them too many times. The task checks accurate letter counting and careful discrimination between similar looking words.

Given Data / Assumptions:
- Base word: COMMUNICATION.
- Letters present: C, O, M, M, U, N, I, C, A, T, I, O, N.
- Frequency counts: C(2), O(2), M(2), U(1), N(2), I(2), A(1), T(1).
- We may not use any letter more times than it appears here, and we may not introduce new letters.

Concept / Approach:
Again, the idea is to compare letter frequency requirements of each option with the available counts in the base word. Because only one option is meant to be constructible, others will usually contain letters like R, Y or D that do not appear in COMMUNICATION at all, or they will require too many instances of a certain letter. A systematic frequency check prevents careless errors that can arise from superficially similar spellings.

Step-by-Step Solution:
Step 1: List the base word counts: C(2), O(2), M(2), U(1), N(2), I(2), A(1), T(1). Step 2: Check AMMUNITION: letters A, M, M, U, N, I, T, I, O, N. Step 3: Requirements for AMMUNITION are A(1), M(2), U(1), N(2), I(2), T(1), O(1). Step 4: All these counts are satisfied by the base word. Therefore AMMUNITION can be formed from COMMUNICATION. Step 5: Check MONITOR: letters M, O, N, I, T, O, R. This requires R(1), but R does not appear in COMMUNICATION, so MONITOR cannot be formed. Step 6: Check COUNTRY: C, O, U, N, T, R, Y. Letters R and Y are missing from the base word, so COUNTRY cannot be formed. Step 7: Check UNIFICATION: U, N, I, F, I, C, A, T, I, O, N. This requires F which is not present in COMMUNICATION, so UNIFICATION cannot be formed. Step 8: Check CONSUME: C, O, N, S, U, M, E. Letters S and E are not present in the base word, so CONSUME cannot be formed.

Verification / Alternative check:
A quick verification is to try to physically spell AMMUNITION using letters from COMMUNICATION by crossing them off as they are consumed. You will see that all required letters can be accounted for. Attempting the same process with MONITOR, COUNTRY, UNIFICATION and CONSUME fails when you search for letters such as R, Y, F, S or E which are not in the base word. This cross-check supports the original frequency based conclusion.

Why Other Options Are Wrong:
Options B (MONITOR), C (COUNTRY), D (UNIFICATION) and E (CONSUME) all require at least one letter that COMMUNICATION does not possess. As a result, none of them can be constructed from the base letters. Only option A (AMMUNITION) uses exactly the letters available in COMMUNICATION and respects their maximum counts, so it is the sole valid construction and hence the correct answer.

Common Pitfalls:
Candidates often focus on shared prefixes like COMM and COMMU and assume that any long similar looking word is possible. This can be misleading because only letter availability matters, not visual resemblance. Another common mistake is to ignore letters that appear only once, like A or T, which may be required multiple times in an option. Use a simple frequency list and check each option carefully to avoid these traps.

Final Answer:
The only word that can be formed by using the letters of COMMUNICATION is AMMUNITION.
